About the Job

Requirements

  • Expert-level Kotlin and Android expertise, with a platform/SDK perspective.
  • Strong knowledge of Android Bluetooth Low Energy, including permissions, background restrictions, and variation across operating-system versions and manufacturers.
  • Comfort with real-time network protocols such as MQTT.
  • Solid experience in software architecture, design patterns, modularity, and dependency injection.
  • Based in Lille and willing to test code on sports equipment near the office.

Responsibilities

  • Design and evolve a decoupled, scalable Kotlin architecture that allows new product types to be added without rewriting the system core.
  • Manage Android Bluetooth Low Energy connectivity for local use, including lifecycle, scanning, reconnection, and manufacturer and ROM-specific behavior, as well as MQTT/REST cloud communication.

  • Enable quality assurance teams to validate SDK features in isolation.
  • Integrate simulation and mocking tools to test hardware error cases that are difficult to reproduce in real conditions.
